Hello Geena.
There a a couple hundred things that can turn on the check engine light.
The only way to find out is to have the computer system scanned by a devise capable of reading these.
In the USA several auto supply stores will do this scan for free.
They do this service free in order to make a sale on whatever part needs to be repaired.
Find out what code or codes are stored and they may suggest the repair procedure.

When the change oil light comes on it is due for service. Time has run out.
I would suggest you take it in as soon as it is convenient.

Thank you for using FixYa.
Happy New Year.

Chances are that the light is coming on in response to a faulty oxygen sensor or something else that will not have a direct effect on performance or fuel economy. It will effect emissions though, so the truck will pollute more than usual and may not pass a state inspection. The only way to be certain is to have the OBD computer read by your mechanic, dealer, or parts store. Many parts stores will "pull the codes" at no charge.

I have a 2003 gmc Sierra half ton 4.8 liter that has a knock that sounds like lifters


There is,If you do the lifter you could be after something else,The noise sounds like a collapsed lifter,A collapse lifter can cause a misfire,The 2003 GMC sierra or I should say the 4.8 engines suffer from a cut O-ring between the oil pump screen and the oil pump causing oil areation,resulting in lifter noise,The noise will be present a cold start and then diminish at warm up.12_3_2012_8_08_44_am.gif

So what do you see come on besides the parking lights? Do you see the high beams come on when you turn them on, do you see low beams or can you see the day time running lights come on (they are the ones that are closest to the grill). What have you done or checked so far?
